ADOLPI-I JORDAN AND FRED SCHINGEL, OF ST. LOUIS, MISSOURI COWL..

SPECFICATION forming part 0f Letters Patent No. 680,865, dated August 20, 1901. Application filed November 24, 1900. Serial No. 37,645. (No model.)

To @ZZ whom. t may concern.'

Be it known that we, ADOLPH JORDAN and FRED SCHINGEL, citizens of the United States, residing at St. Louis, in the State of Missouri, have invented new and useful Improvements in Cowls, of which the following is a specification.

This invention relates to new and useful improvements in cowls or hoods for ventilating systems and its primary object is to provide a device of this character of novel construction having a vane, whereby the same will always stand with the inlet pointed so as to receive the wind.

A further object is to so construct the cowl that the inlet thereto may be open ed or closed from a point therebelow.

The invention consists in certain features of construction and combination of parts, which Will be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of our invention, and in which- Figure 1 is a central vertical section through the device.V Fig. 2 is a top plan view thereof. Fig. 3 is a section on the line :r ce of Fig. 1. Fig. 4. is a detail View of one of the wings of the inlet.

In the drawings the same reference characters indicate the same parts of the invention.

1 is a stationary cylindrical tubular portion of suitable length, having transversely-ex tending braces 2 arranged therein at points adjacent to each end and provided with an aperture 3 in one side thereof, which is adapted to be closed by means of a suitable slide 4. or in any other suitable manner. An upright 5 is secured to the braces 2 and extends upward from the center of the top of the cylindrical portion 1. The upper end of this upright is tapered, as at 6, and is adapted to bear within a recess 7, formed within the lower face of a block 8, preferably formed of glass and secured wi thin the head 9 of the cowl at a point in vertical alinement with the center of the cylindrical portion 10 thereof.

A brace 11 extends transversely of the cylindrical portion 10 of the head, at a point adjacent to the end thereof, and is mounted within an annular groove 12, formed within a collar 13, which is secured to the upright 5, before referred to. It is obvious that the collar 13 will prevent vertical movement of the brace 11, and it is therefore impossible for the head 9 to be accidentally removed from the lower cylindrical portion 1 of the cowl.

A passage 14. extends through the collar 13, and slidably mounted therein is a rod l5, which extends downward through the braces 2 and is secured at its lower end to a chain 16 or other flexible device, which passes over a pulley 17, suspended from the lower brace 2. This chain is adapted to extend down'- ward to the point from which the cowl is to be operated, and a second chain 1S extends downward to said point direct from the rod 15 without passing over the pulley.

An inner cylinder 19 is arranged within the lower end of the head of the cowl and is adapted to extend into the upper end of the cylindricalportion l. This cylinder 19 is connected to the outer cylindrical portion 10 of the head by means of a partition or iiange 20, which is formed at the upper end thereof.

Secured to the upper end of the rod 15 is a block 21, which is adapted to bear upon the lower surface of a flange 22, extending from a sleeve 23, which is loosely mounted upon the upright 5. A hook 24. extends from this block and over the iiange 22 and is adapted to bear upon the upper surface thereof. This Sleeve 23 is connected by means of a link 25 to a bell-crank lever 26, which is pivoted upon a rod 27, extending transversely of the inlet 28 of the cowl. To each side of this inlet is hinged a shutter or wing 29, each of which is provided at its upper and lower edges with a flange 30, and said franges are adapted when the wings are swung toward each other to overlap, thereby closing the spaces formed between the upper and lower edges ot' the wings.

A rod 3l connects each of the wings with the free end of the bell-crank lever and will, as is obvious, cause the same to swing toward each other when the lever is swung inward upon its fulcrum.

A vane 32, which may be of any suitable construction, extends from the outer surface of the head' 9 at a point opposite to but in alinelnent with the center of the inlet. Itis obvious that this vane will hold the inlet pointed toward the wind at all times, the head 9 swinging upon the upright 5.

When it is desired to close the inlet, the chain 18 is pulled downward. This will cause the rod 15 to slide through the collar 13, and the hook 2e will contact with the upper sur- IOC face of the flange 22 of the sleeve 23 and dra-w the same downward. This movement will cause the bell-crank lever 26 to swing inward: upon its fulcrum, and the wings 29 will be drawn toward each other by the rods 27. In order to open the inlet, it is merely necessary to pull the chain 1G downward, and this will cause the operation of the rod, bell-crank 1ever, and the wings to be reversed.

It is of course understood that the cylindrical portion l of this cowl is adapted to be fitted in any suitable manner to an ordinary cylindrical section of pipe or to any other device capable of conducting air. By providing the inner cylinder 19 within the head and the flange 2O thereof wind is prevented from passing into the cowl through the joint.

When it is desired for any purpose to obtain access to the interior of the lower portionA of the cowl, it ismerely necessary to open theaperture 3.

By employing this device air can` be conducted from a point above the roof of a structure down through suitable air-distributing pipes or passages and can be utilized for cooling purposes, dac.

In the foregoing description we have em.-

bodied the preferred form ofl our invention;

but we do not wish to be understood as limiting ourselves thereto, as we are aware that various modifications may be made therein without departing from the principle or sacrificing any of the advantages of this invention;

Having thus described the invention,what is claimed, and desired to be secured by Letters Patent, is-

l. The combination witha stationary tubu? lar portion; of an upright secured therein; a

head revolubly supported upon saidf standard, and extending over theupper endof the stationary portion; a cylinderhaving an upwardly projecting annular iange secured Within the head and depending into the upper end' of the stationary portion; a grooved collar on said standard; wings located at thev inlet ofthe head; a movable sleeve on said standard; connections between said wings and sleeve; and a rod extending through the collar for moving the sleeve.

2. The combination with a stationary tubular portion; of an upright secured therein and extending therefrom, a revoluble head bearing upon the upright and having an inlet, a sleeve slidably mounted upon theupright, wings hinged to the sides of the inlet,v

a lever fulcrumed within the head, a link connection between one end of said lever and the sliding sleeve, rods connecting the remaining end of the lever and each of the wings, and means for sliding the sleeve upon the upright.
